[Lighttpd] Config lighttpd support SSL

Test on FreeBSD 7.2
lighttpd-1.4.22 (ssl) - a light and fast webserver
Build-Date: Apr 18 2009 13:02:03

1. Generate key
#mkdir /etc/ssl/private
#cd /etc/ssl/private/
#openssl req -new -x509 -keyout lighttpd.pem -out lighttpd.pem -days 365 -nodes

2. vi /usr/local/etc/lighttpd.conf
# Uncomment mod_redirect in server.modules.

$SERVER["socket"] == "0.0.0.0:443" {
#### SSL engine
ssl.engine = "enable"
ssl.pemfile = "/etc/ssl/private/lighttpd.pem"
}
else $HTTP["host"] =~ "(.*)" {
url.redirect = ( "^/(.*)" => "https://%1/$1" )
}


3. Start lighttpd
#/usr/local/etc/rc.d/lighttpd restart

[Nokia] E71 ใช้ battery มากกว่าปกติเพราะ garmin xt

h**p://dotdoh.com/?p=394


If you have just installed Garmin Mobile XT version 5.0.0.20 on your Mobile Phone (So far only verified on my Nokia E71 running Symbian OS), you may have notice that your battery life for you mobile phone seems to have reduce substantially from about 2 days before the installation to about 1 day.

This it seem is due to a background process that Garmin Mobile XT starts upon boot up of your Symbian operating system as well as upon running of the Mobile XT software.

Things you will need to verify if you are affected by this background process.

1.) An installed version of Garmin Mobile XT (Duh….)

2.) JBak Task Manager. (You can download it from: http://jbak.ru/jbaktaskman_en.php)

Step 1 Start JBakTaskMan
Step 2 Select Menu >> Tools >> Processes
Step 3 Type TSRAutoStart.exe

If the process TSRAutoStart.exe is found, you are most likely affected by this background process wasting away your battery life.

How to kill the TSRAutostart?

Step 1 Follow the previous Step 1 – 3
Step 2 Select the process TSRAutoStart.exe
Step 3 Select Menu >> Terminate process

How to prevent TSRAutostart from auto loading upon boot up.

Step 1 Plug mobile phone to PC under Mass Storage mode (! important as directories used are otherwise hidden)
Step 2 Delete file CardRunner.RSC in directory under Mobile Phone\Resource\plugins\CardRunner.RSC
Step 3 Delete the file CardRunner.dll in directory under Mobile Phone\sys\bin\CardRunner.dll

Permanent Fix.

Well if you are seeking a permanent fix, you could always try downloading the latest version of Garmin Mobile XT (Link: http://www8.garmin.com/support/collection.jsp?product=010-11034-00).

As of version 5.0.0.40, this background process is now an option that can be switched off, saving you the trouble of killing the process each time you run Garmin.

Step 1 Start GMobileXT (Duh…)
Step 2 Goto Tools >> Settings >> System
Step 3 Scroll down all the way till you see the option “Launch background service”
Step 4 Select Disabled then Done to save


h**p://www.symbian-freak.com/forum/viewtopic.php?p=440972

After installing v5.0.0.x0:

Turn OFF your S60
Turn S60 back ON
Launch JBak Taskman to see if TSRAutoStart.exe is running in Memory in Menu -> Tools -> Processes even though it's set as DISABLED by default in Tools -> Settings -> System -> Launch Background Services.


If TSRAutoStart.exe is running after S60 is turned ON, do this:

START GarminMXT v5.0.0.x0, goto Tools -> Settings -> System -> Launch Background Services and change to ENABLED.
EXIT GarminMXT, re-start GarminMXT and goto Tools -> Settings -> System -> Launch Background Services and change to DISABLED
Turn OFF S60
Turn ON S60
Launch JBak TaskMan to check that TSRAutoStart.exe ISN'T in Menu -> Tools -> Processes

Now:

START GarminMXT v5.0.0.x0
EXIT GarminMXT
Launch JBak TaskMan to check that TSRAutoStart.exe ISN'T in Menu -> Tools -> Processes

Now, you should find:

TSRAutoStart.exe doesn't start when you first turn ON your S60
TSRAutoStart.exe now CLOSES automatically when you exit GarminMXT v5.0.0.x0
It appears that GarminMXT v5.0.0.x0 when being installed, doesn't create the DISABLED entry and has to be done manually by setting to ENABLE, then DISABLE.

[Linux] script สำหรับ check process แบบง่ายๆๆๆๆ

สืบเนื่องมาจากเปิด transmission-daemon ไว้แล้วมัน crash บ่อยเลยอยากให้มี script ไว้ตรวจสอบแล้ว restart อัติโนมัติ

$vi psmon.sh
#!/bin/sh

pid=`ps -ef|grep transmis|grep -v grep|awk '{print $2}'`
if [ -z "$pid" ]; then
echo "Process NOT running, Start process now!"
/etc/init.d/transmission-daemon restart
date >> /home/ubuntu/Ubuntu/psmon.log
else
echo "Process running"
fi



$chmod 755 psmon.sh
แล้วเรียก script ใน crontab ทุกๆ 5 นาที
$crontab -e
*/5 * * * * /home/ubuntu/Ubuntu/psmon.sh

[Linux] ใช้ wireshark บน text mode

ผมติดการใช้งาน wireshark แต่พอดีมาใช้บน linux แล้วเป็น text mode command line ใช้ tcpdump มันแสดงผลไม่สวยเห็น wireshark มีบน text เหมือนกันชื่อ tshark

install
$sudo apt-get install tshark
$sudo tshark -i eth0 -V -f "host 192.168.1.1"
ตัวอย่างมีการ capture interface eth0 โดยมี filter ที่มี src หรือ dst เป็น 192.168.1.1 แล้วแสดงผลเป็น tree คล้ายๆ GUI

[Cisco] QoS ทำการ marking ค่า DSCP แล้ว ไม่เห็นค่าที่ mark

Diagram

[SERVER]-----------[CAT1]---------------[CAT2]----------[CLIENT]

อุปกรณ์เป็น Cisco Catalyst6509 มีการ marking input packet จาก SERVER ที่ตัว CAT1 แล้วมาจับ packet ที่ client พบว่า packet ค่า dscp เป็น 0
เนื่องมาจากว่า catalyst6509 มีค่า default ในการ rewrite packet ToS->DSCP
โดยดูจาก command: show mls qos
QoS is enabled globally
QoS ip packet dscp rewrite enabled globally <---- by default
Input mode for GRE Tunnel is Pipe mode
Input mode for MPLS is Pipe mode
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes


----- Module [5] -----
QoS global counters:
Total packets: 1795932
IP shortcut packets: 0
Packets dropped by policing: 0
IP packets with TOS changed by policing: 459413
IP packets with COS changed by policing: 57
Non-IP packets with COS changed by policing: 0
MPLS packets with EXP changed by policing: 0

จึงทำให้มีการ rewrite ค่าของ DSCP ที่เรา mark ไว้ตั้งแต่ CAT1 เป็นค่าที่ได้จากการ map ToS ค่าจึงเป็น 0 (พูดถึง default mapping จาก ToS->DSCP)
แต่ถ้าต้องการ disable ทำได้ 2 วิธีคือ
1. ตัว CAT2 ที่ global config mode
conf t
no mls qos rewrite ip dscp

!verify
sh mls qos
QoS is enabled globally
QoS ip packet dscp rewrite disabled globally <--- disable
Input mode for GRE Tunnel is Pipe mode
Input mode for MPLS is Pipe mode
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes


----- Module [5] -----
QoS global counters:
Total packets: 3631461
IP shortcut packets: 0
Packets dropped by policing: 0
IP packets with TOS changed by policing: 550481
IP packets with COS changed by policing: 169
Non-IP packets with COS changed by policing: 0
MPLS packets with EXP changed by policing: 0


2. ตัว CAT2 ที่ interface ที่ต่อกับ CAT1
interface x/x
mls qos trust dscp
